The drawing states that the net length of the master bedroom is 5.8 Meters. Zhou Heng retested three times, and her laser ruler only reached 5.22 Meters.
The fifty-eight centimeters missing are in the wall.
The property manager advised her to write it as a decoration error, and the owner waited for the work to start the next day. Her former employer also taught her how to write "existence" as "suspect".
She didn't write it that way.
Behind the wall is not a secret room, but a sealed mezzanine. There is a row of children's height lines on the old wall. One of the names appeared in the local co-investigation information three years ago; next to the highest line is written "Xiao Man, I have grown taller", and the date is last month.
Zhou Heng did not investigate the case. She was only responsible for writing clearly the facts she had seen and measured with her own hands, and then signed her name.
